When VSA starts up, it obtains Product ID (PID) from CIMC to check if H/W is Nexus1010 or not.
If PID is not Nexus1010, VSA stops bootup. At that time, the following logs are shown in console.
Booting from Hard disk
Not a Nexus1010 HW
Not a Nexsu1010 HW
Not a Cisco Virtual Service Appliance HW
If CIMC is unresponsive for some reason, VSA cannot obtain PID. As a result, VSA fails to boot.
To start VSA, Nexus1010 H/W reset is needed to reset CIMC.
These are typical defects causing CIMC unresponsive:
CSCtn06772 CIMC - does not respond - cannot access via SSH / HTTP / HTTPS
CSCts42866 SD/SM: Unable to show detail in any scope during regression
CSCub25194 Memory leak and page fault in CIMC by SSH
